Product Description
General purpose
The ITL231A Mine Detector is convenient, compact, durable, portable equipment for effective detection of buried anti-personnel and anti-tank mines. Improve electronics provides automatic detection of mines in different soils. The ITL231A Mine Detector allows to detect metallic mines, non-metallic mines, also plastic mines with small metal pieces.
Principle
The ITL231A Mine Detector measures the travel time of electromagnetic impulses in subsurface materials. An impulse radar system radiates repetitive electromagnetic impulses into the earth. A broad bandwidth antenna is usually placed in close proximity and electromagneticaly coupled to the ground surface. It is able to detect and measure the depth of reflecting discontinuities in subsurface soils and other earth materials to within a few centimeters depending upon the electromagnetic parameters of the earth medium, the depth to and size of the target and the frequency of operation.
Units
The ITL231A Mine Detector consists of the following units:
Control unit. Pentium-133 CPU or higher.
Display. Includes Planar 1/4 VGA
Antenna unit. For radiating and receiving short pulses. Provides sampling conversion of receiving signals. Includes keyboard. Antenna’s length 1.0 to 1.8 m.

Cables. For assembling of Mine Detector
Operator Manual. User Documentation
Identification procedure
Identification procedure includes the following steps:
Teaching. An acquired information describing behaviors of known mine in different medias (velocity) and on different depths stores into memory of the Mine Detector. An information about all points where mine was tested forms independent file in the Main Library of the Mine Detector. This file can be completed, erased or copied to the Working Library of the Mine Detector.
Detection. he Mine Detector identifies unknown underground objects and gives estimation how close these objects are to any known mine written into the Library.
Identification algorithms. The Mine Detector uses some algorithms for identification od the mine. They are: Linear Prediction Coding (LPC) algorithm, Fast Fourier Transforming (FFT) of LPC algorithm, FFT algorithm, Reflection algorithm, Auto Correlation algorithm, Square algorithm.
